    GENERAL SAFETY PRECAUTIONS be activated manually by the movement of your left hand. • In the felling position the left hand is in a position that makes manual activation of the chain brake impossible. With this type of grip, that is when the left hand is placed so that it cannot affect the movement of the front hand guard, the chain brake can only be activated by the inertia action.

    GENERAL SAFETY PRECAUTIONS Right hand guard Apart from protecting your hand if the chain jumps or snaps, the right hand guard stops branches and twigs from interfering with your grip on the rear handle.

    GENERAL SAFETY PRECAUTIONS • Check that the bar tip sprocket turns freely and that the lubricating hole in the tip sprocket is not blocked. Clean and lubricate if necessary. If the chain lubrication system is still not working after carrying out the above checks and associated measures you should contact your servicing dealer.

    Fitting the bar and chain WARNING! Always wear gloves, when working with the chain. Check that the chain brake is in disengaged position by moving the front hand guard towards the front handle. Remove the bar nuts and remove the clutch cover (chain brake).

  • Page 18: Fuel Handling

    When working with continuous high revs (e.g. limbing) a higher octane is recommended. Environment fuel HUSQVARNA recommends the use of alkylate fuel or environmental fuel for four-stroke engines blended with two-stroke oil as set out below. Note that carburetor adjustment may be necessary when changing the type of fuel (see instructions under the heading Carburetor).
